From 869b9eddf0b38a22c27a400e2fa849d2ff2aa7e1 Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Mon, 16 Jan 2023 12:08:44 +0200 Subject: mfd: intel-m10-bmc: Add PMCI driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the mfd driver for the Platform Management Component Interface (PMCI) based interface of Intel MAX10 BMC controller. PMCI is a software-visible interface, connected to card BMC which provided the basic functionality of read/write BMC register. The access to the register is done indirectly via a hardware controller/bridge that handles read/write/clear commands and acknowledgments for the commands. Previously, intel-m10-bmc provided sysfs under /sys/bus/spi/devices/... which is generalized in this change because not all MAX10 BMC appear under SPI anymore.
